SIGNAL.

Specification of Letters Patent.

Patented Feb. 19, i918.

Application filed Jiune 12,1917. Serial No.1174,212.

To all whom t may concern:

Be it known that I, JAMES C. CHESTER, a citizen of the United States', residing at Escalon, in the county of San Joaquin, State ot' California.' havev invented certain new and uset'ul Improvements in Signals; and I do declare the following t0 be a full, clear, and exact description of the saine, reference being had to the accompanying drawings, and. to the characters' of reference marked thereon. which t'orm a part'of this applica tion.

rl`his invention relates to improvements in signals and particularly t0 a vsignal adapted to be mounted upon a vehicle whereby the. driver of such `vehicle may ive an indication to other vehicles or pe estrians to the front or rear of him that he is about to turn. The invention will be preferably mounted at or near the driving seat of the? vehicle and is easily operable by hand to extend the same. When not in extended posi` tion it is held within the casing by resilient means of desired type; A light is provided at the end of the signal whereby it can be readily seen in the dark.

A great many accidents occur due to the l fact that vehicles turn or stop suddenly without giving any previous indication that 'they are about to do so. Laws have been enacted requiring the driver of a 'vehicle to extend his hand but this is often inconvenient and in inclosed cars is impossible. My improved signal however, will be much more efiicient than the extending of the hand and at the same time will not require the driver to let go of his steering wheel at a time it is very essential that he have full control ot' his vehicle and at the same time can be quickly and easily extended atvany moment to show the direction the driver intends to turn at his first opportunity.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed, to give a warning toV alLyin plenty of time as to the intention of the driver. i

rlhese objects l accomplish by means of such structure and relative arrangement of parte as will fully appear by a perusal' of the following specification and claims.

1n the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a front elevation of a motor vvehicle showing my improved mechanism 'suitable manner is a pin 2 having for a portion of its length a spiral bar 3. The numeral l designates a small roller having a central slot 5. on each side of which is a small roller 6 whereby the roller f1 may mov@ easily in a rotary'manner up and down the spiral bar 3. This roller 4 is held in its uppermost position on the spiral bar 3 by means ot' a coil spring 7 linterposed between the top ofthe casing 1 andthe roller 1 so as to pull such roller upwardly. Rolled up on the roller 4 is a signal liag 8, the rolled up position of such flag 8 being occasioned by the rotary motion ot' the said roller 4 in the manner described. When not4 in use the flag 8 is rolled on the said roller l within the casing l. When it is desired to extend the flag. however7 this is accomplished by I'neans of the following structure and operation, namely: A hand button 9 is provided with a pin ll0 turnably disposed through the casing'l. On this pin 10 within such casing 1 is secured a rod 11 pivotally connected at its opposite end with 'the Hag 8 as at 12. lVheu it is desired to extend the signal the member 9 is turned which turns the pin 10 and moves the rod 11 out of the casing 1 in an are. Since the rod @is pivotally'connected to the flag 8 this 'unrolls such Hag 8 and extends it substantially in the manner shown in Figs. l and 2. As the flag 8 is unrolled it ot course must likewise describe an'arc to conform to the arc as described by the rod 11. |This is permitted of by the roller 4 moving downwardly on the spiral bar 3. 1When onceextended the signal may be held in that position by means of a small lug 13 on a collar 14 -ixed to the pin 10 which lug engages a corresponding groove a the casing. rEhe pin l@ is movable 1ongitudinally through the casing l against the pressure of a spring l5 whereby the lug 13 may be engaged or disengaged Withthe corresponding groove. In the outer end of the rod 11 is an electric la-mp 1G which is prol vided with suitable Wire connections whereby at night the lamp will be lighted when the signal is extended. These electrical connections will be'of a general type hence I do not here specifically describe the same. When the signal has served its purpose the operator grasps the member 9 and presses the pin l0 against the pressure of the spring l5. This releases the lug 13 from its groove and the spring 7 then pulls all the parts back into folded positionA within the casing l ivhere they remain until again extended in the manner described. A

From the foregoing description it will be readily seen that I have produced such a device as substantially lfulfils the object of the invention as set forth lie-rein.

While this speeiiieation sets forth in detail the present and preferred construction ofthe device, still in practice such deviations from such detail may be resorted to as do not form a departure from the s of the invention, as defined bythe claims.

Having thus described my invention what pirit appended I claim as new and useful secure by Letters Patent is:

l. A signal comprising a easing, a spiral bar mounted in the casing, a roller mounted for vertical and rotary motion on the bar, a flag wound on the roller, and means for moving the roller over the bar to unwind the flag thereon.

2. A signal comprising a casing, a spiral bar mounted in the i '.sing, a roller mounted for vertical and rot; ry motion on the bar, a fiag wound on the roller, and means for moving the roller over the bar tounwind the Hag thereon, such means including a pivoted rod connected with the free end of the Hag and means for moving the rod 0n its pivotal point.

3. A signal comprising a casing, a spiral bar mounted in the easing, a roller mounted for Vertical and rotary motion 011 the bar, a flag wound on the roller, and means for moving the roller over the bar to univind the flag thereon, such 'means including a pivoted rod connected with the free end of the flag and means for moving the rod on its pivotal point, and fixing it in a position to hold the flag extended. Y

In testimony whereof I aliix my signature.

JAMES o. CHESTER.
